Introduction Recently, the mobile business professionals have been more and more looking for an efficient way to access corporat

29、e information systems and databases remotely through the Internet backbone. However, the high bandwidth demand of the typical office applications, such as large email attachment downloading, often calls for very fast transmission capacity. Further, certain hot spots, like airports and railway statio

30、ns are a natural place to use the services. However, in these places the time available for information download is typically fairly limited. In the light of above there clearly is a need for a public wireless access solution that could cover the demand for data intensive applications and enable smo

31、oth on-line access to corporate data services in hot spots and would allow a user to roam from a private, micro cell network (e.g. a HIPERLAN/2 Network) to a 3G cellular network. Together with high data rate cellular access, HIPERLAN/2 has the potential to fulfil end user demands in hot spot environ

32、ments. HIPERLAN/2 offers a possibility for cellular operators to offer additional capacity and higher bandwidths for end users without sacrificing the capacity of the cellular users, as HIPERLANs operate on unlicensed frequency bands. Also, HIPERLAN/2 has the QoS mechanisms that are capable to meet

33、the mechanisms that are available in the UMTS systems. Furthermore, interworking solutions enable operators to utilize the existing cellular infrastructure investments and well established roaming agreements for HIPERLAN/2 network subscriber management and billing.

The present document

35、 describes the requirements and architectures that are applicable to interworking between High Performance Radio Local Area Network HIPERLAN/2 and 3d Generation Cellular Systems. The requirements in the present document address subjects such as operational requirements, user requirements, mobility,

36、QoS mapping, subscription information, equipment identity, security and standardization requirements. The architectures address communications layer models as well as the reference models that identi6 interfaces and issues subject to standardization. 2 Re fe re nces For the purposes of this Technica
